So I've been having a few days of intense itching down there. I itched with my last period and thought maybe my ph was just whacked or I was getting a YI. But now.... there seems to be this new found little flap of skin or something I've never felt before at the top of my vagina opening. I have no clue what it is or why it itches so badly. Like if I touch it to check if it's changed, I'm up for hours itching and almost in tears. Itch cream won't help at all. My. Oh friend took some pics and looked around he said somthing about looks like it has a small hole in it? I have no idea. I can't tell what's going on via the pictures. I'm at wits end. If it doesn't let up soon I'll go to the gyno. Just trying to hold off til payday on the first. Anyone ever had anything similar? Or any ideas? I dont think it's excess hymen or whatever google did since I've been regularly sexually active since 16 and am now 24...
